Pneumatic control valve installation guidelines:

(1) pneumatic control valve installation position, from the ground requires a certain height, the upper and lower valve to leave some space for valve disassembly and repair. For vehicles equipped with pneumatic valve positioners and gas Valve Manufacturer hand wheel, must ensure that the operation to observe and easy to adjust.

(2) The control valve should be installed in horizontal pipelines, and up and down with the pipe vertical, generally under the valve to be supported, to ensure stable and reliable. For special occasions, the level of need regulating valve installed in a vertical pipe, the valve should also be supported (except for the small-diameter valve). Installation, to avoid additional stress caused to the control valve).

(3) temperature control valve in the working environment (-30 ~ + 60) 95% relative humidity less than 95% relative humidity less than 95%.

(4) before and after the valve position should be straight pipe length is not less than 10 times the pipe diameter (10D), in order to avoid valve straight pipe is too short to affect the flow characteristics.

(5) and process control valve diameter pipe is not the same, different-diameter pipe should be connected. Control valve installed in a small diameter, the threaded connection is available. Direction of the arrow on the valve body fluids should be fluid in the same direction.

(6) To set the bypass pipe. Purpose is to facilitate the switch or manual operation, in the case of non-stop valve repair.

(7) control valve in the pipe prior to installation to completely remove the foreign body, such as dirt, welding slag. How it works:

Pneumatic control valve is driven by compressed air source to the cylinder for the actuator and valve positioner by means of electrical, converters, solenoid valves, valves and other accessories to secure his position to drive the valve to achieve the switch or proportional adjustment, Industrial automation and control systems to receive the control signal to adjust the pipe to complete the media: flow, pressure, temperature and other process parameters. Pneumatic control valve is characterized by simple, rapid response, and intrinsically safe, explosion-proof without the other and then take measures. Storage Installation Precautions

1 The valve should be stored in a dry room, access must be blocked at both ends. Allowed to pile storage

(2) long-term storage of the Gas Cooker valve should be checked regularly to remove dirt, some in the movement and processing of the surface to be coated with anti-rust oil, to prevent rust.

3 The valve should be installed in horizontal pipelines, vertical installation required. Stem up.

4 required by the arrow icon to indicate flow direction of the installation.
